Not that anyone thought otherwise but I will confirm the total monies donated to my iPod replacement program:

$0.00

No surprise there.

No surprises here either these days so move along. Might I suggest you go read about A First-Quantized Formalism for Cosmological Particle Production?

Abstract:
We show that the amount of particle production in an arbitrary cosmological background can be determined using only the late-time positive-frequency modes. We don't refer to modes at early times, so there is no need for a Bogolubov transformation. We also show that particle production can be extracted from the Feynman propagator in an auxiliary spacetime. This provides a first-quantized formalism for computing particle production which, unlike conventional Bogolubov transformations, may be amenable to a string-theoretic generalization.

My pal worked on that.

Check out heroecs, the robotics team competition website of my old supervisor's daughter. Fun stuff!
